I guess it depends on what company is selling em..
iTunes is paying .65, but MusicNet only pays .02.
If it's a physical CD that gets sold I get about $10 through CDBaby but only $8 through BestBuy. If I sell em through my own site I get $13 for a CD and .69 to 1.99 for songs.
Whatever.... I'm happy... free beer money :D
